A more accurate title would probably be "120M stolen from hacked South African bank via 1,400 convenience store ATMs across Japan"
13M was not stolen. 12M was stolen (and some more).
Thus the more accurate title would be "12M stolen from hacked South African bank via 1,400 ATMs across Japan" since the statement in your title is demonstrably false, while the other title is (presumably, from the article) true.
